1) platform is win xp

2) Indeed, reflections is not needed (was trying out some things there, and forgot to put back the original code)

Weird thing is , I tested it now and… IT WORKS!!!

Only problem still : where overlaps are present, I see 2 flickering black bands (not always in the same position).

Any idea why?

mandel answered your question: Why java opaque and opengl don’t mix???

One question, actually 2, which platform? and why are you calling Class.forName? I think you do not need reflection for that AWTUtilities
